A roofing membrane and a method of making the same is provided. The roofing membrane includes a top layer having a flame retardant and a first silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3; a scrim layer; and a bottom layer having a flame retardant and a second silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3. The top and bottom layers of the roofing membrane both exhibit a compression set of from about 5.0% to about 35.0%, as measured according to ASTM D 395 (22 hrs @ 70° C.).

A textile barrier apparatus includes an inner layer comprising an aqueous super absorbent polymer composition (SAP) and first and second outer textile layers attached to opposite sides of the inner layer. A landfill version includes an odor neutralizer, a biocide and/or a nutrient to support vegetation. A fire barrier version has the first and second outer textile layers including water permeable membrane and a fire retardant treatment. A planting groundcover version includes a patterned thickness of SAP corresponding to a planting pattern and a nutrient to support vegetation.

A membrane roofing system that includes a waterproof layer that protects an insulation layer and a granule coupled to the waterproof layer. The granule has a 60% or greater reflectivity that reduces transmission of ultraviolet light to the waterproof layer. The granule is coated in a fluorinated acrylic copolymer that resists adsorption and absorption of asphaltic chemicals by the granule from the waterproof layer.

An underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet includes a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film including a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer includes a reactive material capable of reacting with the liquid waterproofing material. The reactive material either (1) includes a functional group capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group capable of reacting with the components of the liquid waterproofing material.

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.
